Abstract

Ultraviolet excimer lasers provide new technology in the correction of ametropias and corneal irregularities. The ultraviolet range laser uses excited dimers to remove or ablate tissue. Procedures that correct myopia, hyperopia and astigmatism are termed photorefractive keratectomy (PRK) and those used to treat corneal irregularities and opacities are called phototherapeutic keratectomy (PTK). The ablative process is highly precise and the surrounding tissue sustains m1mmum thermal damage. Epithelial healing is usually clinically complete within a few days and a slight stromal haze is present for several months. The excimer laser delivery system with its computerized instruments offers practitioners a vital new tool to treat their patients.
